# This script is distributed under the Gnu General Public License (GPL)
# Ce script permet la mise à jour d'un ALCASAR
# - (alcasar-conf.sh -create) : création de l'archive des fichiers de configuration (/var/tmp/alcasar-conf.tar.gz)
# - (alcasar-conf.sh -load) : chargement de l'archive des fichiers de configuration. Le cas échéant, c'est ici qu'on met à jour les fichiers entre versions
# - (alcasar-conf.sh -apply) : application des directives du fichier de conf central "/usr/local/etc/alcasar.conf". Peut aussi être exploité à chaud après avoir changé des valeurs du fichier de conf.
# This script allows ALCASAR update
# - (alcasar-conf.sh -create) : create the configuration files backup (/var/tmp/alcasar-conf.tar.gz)
# - (alcasar-conf.sh -load) : load the backup of configuration files. If needed, it's here we update files between versions
# - (alcasar-conf.sh -load) : apply ALCASAR central configuration file "/usr/local/etc/alcasar.conf". Can be use after changes of conf file values.
